Revert "Add Render Process Sandbox Policy feature tests" This reverts commit cbbfffe534a0017c63f27229096289cb220937c6. Reason for revert: suspect this CL has caused RendererSandboxSettings/RendererFeatureSandboxWinTest.RendererGeneratedPolicyTest to be flaky on multiple bots. Bug: 1209051 Original change's description: > Add Render Process Sandbox Policy feature tests > > This is primarily a Windows change, but some refactoring was necessary > in order to make RendererSandboxedProcessLauncherDelegate usable in test > code and this class exists on multiple flavors. > > Bug: 1266582 > Change-Id: Id9aefb3e3eed2e3e375c8f14e0e90127cb86fc3e > Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3260947 > Reviewed-by: Will Harris <wfh@chromium.org> > Reviewed-by: Jonathan Ross <jonross@chromium.org> > Commit-Queue: Emily Andrews <emiled@microsoft.com> > Cr-Commit-Position: refs/heads/main@{#940462} TBR=jonross@chromium.org,wfh@chromium.org,chromium-scoped@luci-project-accounts.iam.gserviceaccount.com,emiled@microsoft.com Change-Id: I1efbf754758da3eca26b888e3b473b09356a0e3e No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: 1266582 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3273699 Reviewed-by: Will Harris <wfh@chromium.org> Reviewed-by: Olivia Yingst <huiyingst@google.com> Reviewed-by: Yuki Yamada <yukiy@chromium.org> Reviewed-by: Hui Yingst <nigi@chromium.org> Owners-Override: Yuki Yamada <yukiy@chromium.org> Commit-Queue: Olivia Yingst <huiyingst@google.com> Cr-Commit-Position: refs/heads/main@{#940558} NOKEYCHECK=True GitOrigin-RevId: bcd1a8f73f3858472384a24c00b74c2922b0b9f4
This directory contains platform-specific sandboxing libraries. Sandboxing is a technique that can improve the security of an application by separating untrustworthy code (or code that handles untrustworthy data) and restricting its privileges and capabilities.
Each platform relies on the operating system's process primitive to isolate code into distinct security principals, and platform-specific technologies are used to implement the privilege reduction. At a high-level:
mac/ uses the Seatbelt sandbox. See the detailed design for more.linux/ uses namespaces and Seccomp-BPF. See the detailed design for more.win/ uses a combination of restricted tokens, distinct job objects, alternate desktops, and integrity levels. See the detailed design for more.Built on top of the low-level sandboxing library is the //sandbox/policy component, which provides concrete policies and helper utilities for sandboxing specific Chromium processes and services. The core sandbox library cannot depend on the policy component.
